Due to integration processes in Europe, Poland’s accession to the European Union and the Schengen zone, statistic of transborder areas acquires particular importance. It corresponds to the increasing demand for information on areas located on both sides of the border and, at the same time, also serves to promote regional development and transborder cooperation.
